Pixelation on my UV image text
It's cause by your reference image, which is an png image I guess?

PNG(Portable Network Graphic) is not just a simple algorithm but an image storage solutions bucket. There are two main way to implement the thing "Transparency". And you might choose the simpler one:



If I use PNG-8 bit(paletted method) I will got the strange White border. That is actually coming from matte color since paletted method only allow one transparency value instead an alpha channel. When I choose PNG-24 bit(true color with alpha) we get a better image without border.


So you need to redo that image to make the border show as an actual color. Or you can also use your image as alpha material socket input to reduce the white border effect.
